HVAC Contractor helping a couple choose a furnace

What size furnace do I need?

When it’s time to replace your outdated furnace, it’s important to understand one size does not fit all. A system that is not sized correctly for your home, will not only impact your comfort, but can mean a shortened life of your furnace, and leave you spending extra money on your utility bills.

If you choose a furnace oversized for your space, you’ll start to notice short cycles. The reason is that your oversized furnace heated your home too fast, turning off before the furnace can reach the right operating temperatures. An undersized or oversized system can lead to reduced lifespan and bigger expenses.

How can you be sure you know the right furnace size for your home? Begin with a load calculation from the team at M & S Heating & Air LLC. A load calculation takes particulars from your home into consideration and gauges the Btu (a number that indicates the heating capacity of a furnace) required to heat your house.

Some Items that Influence Furnace Size

  • Square Footage—What size is the area your furnace will need to heat? The technician will be sure to carefully measure the square footage of your home. Not every inch of your home will be considered during this process. Usually, it is more beneficial to account only for the space that needs heating.
  • Home Insulation—Insulation assists in keeping warm air from escaping your home throughout the cold winter months. It also greatly affects energy efficiency and how large of a heating system is required. Let the professionals from M & S Heating & Air LLC review the insulation in your walls and attic. They’ll help you choose the ideal furnace for your house.
  • Type of Window— Just like your walls, the particular type of windows in your home, frame type, glaze type, gas fills/spaces, etc. will influence your heating and cooling requirements.
  • Outdoor Climate—Consider the range of weather you experience in Mechanicsville. You’ll want a furnace that can sustain the conditions of your climate every year, without overworking itself.
